For all data collected by the National Health Service there is a standards approval process. This is managed by the Standardisation Committee for Care Information (SCCI), a subgroup of the National Information Board. All mental health data standards are approved via this process and result in an Information Standards Notice being issued which mandates Electronic Patient Record System suppliers and providers of NHS funded services to collect and submit the data.
The Mental Health Services Data Set reference is SCCI0011 (http://www.hscic.gov.uk/isce/publication/SCCI0011). It should be noted that this standard relates to the specification for data flowing from NHS-funded care providers to the Health and Social Care Information Centre for secondary use purposes. The standard has been designed so that it includes only data which can be derived from local clinical records and only data items which need to be directly collected. It also supports the principle that data is collected once and used many times.
In relation to data quality, the Department and NHS England successfully worked with Improving Access to Psychological Therapies providers to ensure consistent data quality. We will take a similar approach as we continue developing the new mental health dataset and would expect the five-year data plan which will inform future data collections on mental health to consider data quality.
